Our history

A journey through time in 18 stages. Click through.

1897
Background

Entrepreneurial spirit across generations

The Treusch family runs a large saddlery in Reichelsheim in the Odenwald, employing around 20 journeymen, and produces gold-embellished harnesses for the carriages of European royal houses. Leonhard Treusch exhibited them at the 1897 World’s Fair in Brussels.

1946
Electrical Engineering

From the lecture theatre to Krupp

His son, Wilhelm Treusch, studied electrical engineering at Darmstadt Technical University and rose through the ranks at Krupp in Essen to become plant manager. On his mother’s side of the family, Weidelt Systemtechnik was founded in Bremen in 1920.

1984
Paul Hasselbach

Hasselbach & Kausch

Paul Hasselbach, a qualified motor winder from the Lloyd shipyard in Bremerhaven and a master electrician, founded Hasselbach & Kausch, the predecessor company to Rotek. In a small, disused hall, he built motors of his own design.

1998
The move

A stable dating from 1927

„I don’t want to work at the fish shop.“

Liane Giesges, first member of staff

Instead of moving to the fishing harbour, the company, with its seven production staff, relocated to a former airfield. The building is thought to have once housed the horses that pulled the aeroplanes to the runway. Rotek is still based here today.

2000
Foundation of Rotek

A handshake in an hour

After an hour-long tour, a handshake seals the takeover of Hasselbach & Kausch. The Treusch family founds Rotek, a name derived from ‘rotation’ and ‘technology’.

2003
Second source of income

Contract with SPG

On 9 April, Rotek will sign a contract with SPG of South Korea at the Hannover Messe and become the exclusive distributor for Germany and Austria.

2006
Growth

The first extension

The floor space is increasing to 1,000 m². This will be accompanied by a new brand identity, including a website, catalogue and promotional film.

2008
Energy-saving motor

ROSYNC goes into mass production

The energy-saving engine with GreenDrive Technology is going into series production. A second extension adds 25 % of space.

2009
Farewell

Paul Hasselbach is retiring

"We build motors not just for profit, but also because we enjoy it!"

Paul Hasselbach

Until then, he’ll be tinkering away at the workbench alongside Wilfried Treusch. We’ll take a leaf out of his book.

2010
Award

Environmental Award for ROSYNC

Rotek received the 2009 „preis umwelt unternehmen: Nordwest“ award for ROSYNC, which was presented in February 2010.

2013
Quiet drives

ROSLYDE goes into mass production

The low-noise motor with SmoothDrive Technology. As quiet as the night, for applications where noise is a nuisance.

2014
Smart drives

ROMOTION goes into mass production

The BLDC motor with integrated control electronics strikes a balance between energy efficiency and power density.

2016
Innovation

Schütting Prize

Third place in the Bremen Chamber of Commerce’s Schütting Prize for Innovation in SMEs.

2019
Stainless steel

ROTECT goes into mass production

The stainless-steel motor for hygienic processes and high-pressure cleaning. In 2020, the company’s premises will become a hub for biodiversity.

2024
Extension

Rotek continues to expand

Planning for the expansion is getting underway: new space for production, offices and a dedicated warehouse.

2025
Anniversary

25 years of Rotek

On 14 February, the whole team will be celebrating amongst the steel framework of the new hall.

2025
New warehouse

350 pallets on our own premises

The new warehouse is now complete. We can now store up to 350 pallets on our own premises, without the need for external service providers. This makes a real difference, particularly in the retail sector.

2026
Today

Ferrite instead of neodymium

ROMOTION is now also available in a rare-earth-free version, developed right here in Bremerhaven. The story continues.

Arrows, dates or swipes guide you through the story.

Everything under one roof

We manufacture almost everything in-house.

1

In-house machinery

We machine and finish our parts ourselves. This means we have full control over quality and can implement bespoke solutions straight away.

2

Installation by experienced fitters

Engines and gearboxes are hand-built and tested on our own test bench before they leave the factory.

3

Own warehouse

Up to 350 pallets stored on-site. Short delivery times and full control over stock levels.
